open a subreport from mainreport by a link

Re: open a subreport from mainreport by a link

You could use an on-demand subreport
On-demand subreports can be especially useful when you want to create a report that contains multiple subreports. In this case, you can choose to have these subreports appear only as hyperlinks.

The actual data is not read from the database until the user drills down on the hyperlink. This way only data for on-demand subreports that are actually viewed will be retrieved from the database. This makes the subreports much more manageable.

I think that You should search about Record or Group Selection, that only will display the selected one(s)
